Question 1

Arteries

Functions + ex.

Answer 1

Carry blood away from heart

Ex. Aorta

Question 2

Veins

Function+ ex.

Answer 2

Carry blood to heart

Ex. Vena cava

Question 3

SA node (sinoatrial node)

Answer 3

Regulates contraction of heart aka. Pacemaker

Question 4

Answer 4

To the lungs

Exchanges CO2 and O2

Question 5

Systemic circulation

Answer 5

To the body

Question 6

Coronary circulation

Answer 6

To the heart

Atherosclerosis- blocked arteries in heart

Question 7

Answer 8

To small intestines and liver

Question 9

Lymphatic system

Answer 9

Returns fluids, filters pathogens

Question 10

Lymph

Answer 10

Fluid found in blood, collects in tissue and must be returned to blood

Question 11

Lymph vessels

Answer 11

Return lymph to blood vessels

Question 12

Lymph nodes

Answer 12

Contain lymphocytes(WBCS) that help destroy pathogens

Question 13

Components of blood

Answer 13

Plasma
Platelets
Erythrocytes (RBCS)
Leukocytes (WBCS)

Question 14

Plasma

Answer 14

90% water

Vitamins, minerals, amino acids, glucose, proteins, hormones

Question 15

Erythrocytes

Answer 15

No nucleus at maturity
Hemoglobin carries oxygen
Live about 120 days

Question 16

Leukocytes

Answer 16

Much larger than RBCS
Phagocytes engulf and destroy pathogens
Some produce antibodies to destroy pathogens

Question 17

Platelets

Answer 17

Clot when blood vessels is cut (stick to wound)
Fibrin (protein) forms sticky heads
RBC’s stick to fibrin and make clot

Question 18

Take- O, B
Give - B AB

Question 25

Type O

Answer 25

No antigens
Antibodies A, B in plasma
Give to everyone
Take -O

No antibodies
Take from everyone
Give to AB

Question 27

Capillaries

Function +ex.

Answer 27

Between arteries and veins

Exchange nutrients, gases, wastes with cells

Question 28

Inspiration- inhalation

Answer 28

Diaphragm moves down, rib muscles contract and move up, increased lung volume, pressure in the lungs decreases, air goes in
